Generous oil ducts extend along the height of the coil to provide cooling in the winding. is a thermally upgraded kraft paper. Layer insulation The Insuldur system of chemical stabilisers thermally upgrades the cellulose insulating materials to permit 12% higher load capacity. diamond epoxy bonds help assure free oil flow through the winding. abrasion resistance and thermal and chemical stability. The large areas presented by the layer-type winding result in a low ground capacity. sound levels by up to 3 dB and iron losses by up to 10%. By minimising this imbalance vertical forces are correspondingly reduced. thus making the design stronger under short circuit stresses. The staggered.Construction features Core The core is a series of laminations made from high-quality. Dimensional changes in the insulating materials are minimised to ensure a tighter structure. The core efficiently fills the opening in the coil. The layer insulation is coated with a diamond pattern of B-stage epoxy adhesive. DuraBIL® maintains its dimensional stability and the coil’s structural integrity. high-impulsestrength coil is the result. Some design considerations may require the use of traditional crepe paper or Nomex® tape as turn insulation. Since DuraBIL® is chemically stable. The rectangular shape of the core can be more uniformly and firmly supported to prevent movement of the laminations so as to improve sound level characteristics. The high to low insulation is fitted over the low voltage winding and the wire of the strap wound high voltage is wound directly over the low voltage to form a high strength coil assembly. which cures during processing to form a high strength bond. Insuldur. The stacked core provides a superior flux path by utilising a step-lap that joins the core legs to the top and bottom yokes. utilise DuraBIL®. A compact. The Insuldur system allows a unit rated at 55°C to be operated at a 10°C higher temperature with a 12% increase in kVA capacity. The effective support for the core together with a step-lap joint have reduced existing currents by up to 40%. The process is closely controlled and monitored to ensure a continuous. it does not degrade or contaminate the transformer fluid with moisture. Unbalanced ampere-turns create forces during short circuits that push the high voltage and low voltage coils apart vertically. Turn insulation ABB power distribution transformers are designed to meet specific performance criteria defined by the customer. This bond keeps the windings from moving during operation or under short circuit stresses.Oil Type Transformers . flexible and inert turn insulation. Coils The coil features a low voltage rectangular wire or sheet conductor extending along the full height of the coil. The result is greater strength and coil integrity throughout the life of the transformer. As a result. The result is a compact turn insulation with superior characteristics including adhesion. The short yoke between the legs of the core reduces the external flow between the active leg core material. which gives a nearly straight line surge distribution throughout the winding.

Galvanic isolation The input transformer isolates the converter from the feeding network and reduces short circuit currents to the converter. ABB offers converter transformers for your every need: Transformers are manufactured as oil-filled. selecting the correct converter transformer has become of vital importance. The transformers have been developed in close co-operation with converter manufacturers and with the aim of achieving the highest possible reliability and efficiency.cascade drives . energy saving. .g. 44 . extended equipment life. e. A symmetrical impedance and the capacity to withstand short circuiting are essential. Choosing the correct converter transformers for different converters and drive systems means reduced downtime. The earthed shield also protects the drive from transient over-voltages coming from the feeding network.cycloconverters (see opposite) .or 24-pulse supply for different converters. ABB offers you a wide range of converter transformers.Transformers for Variable Speed Drives q Input transformers for supply of drive systems 6-.load commutated inverters . The input transformer adapts the medium network voltage to the converter supply voltage. either mineral. They can be manufactured with an output of up to approx. rolling mill drives and similar equipment where only HV motor applications are available.Wind tunnel drives etc. or where low voltage cabling would not be feasible due to losses and voltage drop .Tappings are required to match the drive to different motor voltages or different cable lengths Output transformers are produced in oil type and dry type configurations up to 6 MVA ratings for various types of converter and output voltages up to 15 kV. which is also commonly used. The main parts of a cycloconverter drive are supply transformers. Typical applications for output transformers are when: .Cost of a high voltage converter is too high compared with a low voltage converter and an output transformer (low end rating of the converters) .Transformers for Variable Speed Drives . (Thus the name “converter step-up transformer”.Harmonics reduction Network regulations require reduction of harmonic distortion. Normally the voltage is raised from the Low Voltage converter to feed an HV motor. The following types of transformers are used: . Transformers for cycloconverter supply Cycloconverters are used for high power. icebreakers.Ship propulsion (see below) . They are designed to particular specifications to meet specific space problems (e.Mine hoist drives .The motor does not have a standard voltage converter (retrofit or by-pass application required) . The output step down transformers in the latest applications are submersible i.e.) A standard transformer cannot be used due to variation in frequency. A special step-up transformer has therefore been developed for this application in co-operation with converter manufacturers.4 winding transformers Output transformers for converters Converters are available for only a limited range of standard motor voltages. Nowadays it is also applied to cargo ships.3 winding transformers .Rolling mill drives . low speed synchronous motor drives such as: . the highest being 4 kV. the harmonic distortion and the DC component existing during transients in the output voltage of the frequency converter. they are placed on the seabed close to the motor. ferryboats etc.e. These transformers adapt the generated voltage to the voltage of the static converters which control the motors.Distance from the converter to the drive is long and a high voltage motor is used to reduce cabling costs. Typical applications Most typical applications are for submersible oil pump drives.2 winding transformers . ABB Power Technology Products 45 . Output transformers can also be applied to reduce the voltage at the end of a long transmission system to be more appropriate for a motor.g. high speed circuit breakers and the synchronous motor. Transformers are individually designed and manufactured according to system requirements. the cycloconverter. due to the installation and manoeuvring flexibility of motor groups and for space rationalisation as well as for the improvement in the system’s global performance. Different transformer connections are used to achieve multi-pulse systems with substantial harmonic reduction. A specially designed transformer can be used to transform the converter output voltage to match any motor rated voltage. Ship propulsion systems Electric propulsion for marine applications was initially used on holiday cruises for reasons of comfort (i. The transformer impedance acts as a commutating reactor and thus reduces harmonics. lower vibrations compared to mechanical propulsion). height limitations) and the presence of high harmonic currents as well as mechanical vibrations coming from the ship’s structure. 19400 kVA.

Therefore no standard types are listed. Duplex reactors Duplex reactors are special commutation reactors used in propulsion drives to achieve distortion free voltage in the auxiliary circuits. Two basic designs are used: 1.Tuning (filter) . propulsion and other drives where space and weight limitations are important) are usually fitted with commutation reactors. Reactors for cycloconverter drives Zero sequence reactors Zero sequence reactors are used to limit zero sequence current on motors with galvanically separated windings. Construction features Introduction Sıngle-phase and/or three-phase reactors are characterised by a wide range of solutions found in several High Voltage and/or Medium Voltage installations for both oil-type and dry purposes. The commutation reactors are normally dry-type but can also be manufactured as oil immersed.Damping . The most efficient harmonic reduction is achieved when the duplex reactors are connected to the generators.g.Reactors Duplex reactor for ship-propulsion.
